Java has updated their security parameters, the access to the Open Processing applications have been affected. Open processing team, please verify the certificates, becouse Java is blocking the applications when the users press the run button. This is the message that shows when i try yo run an app: "Application Blocked by Security Settings". The "allow" option isn't available any more :( Its blocked for default for those who don't check their certificates.

I can create an "Upload to OpenProcessing" plug-in for Processing. It would be a menu item under Tools menu in Processing, which would automatically Export your sketch, .zip it, and upload it to your account, and show you your sketch in your browser.

There is an beta API available for accessing and uploading to OpenProcessing, which can be easily used for such a plug-in for Processing. If you would like to help developing this plug-in for OpenProcessing, please contact me at info@openprocessing.org

A way to track 'parentage' of a sketch, when a sketch is derived from another on the site. Implementation: include a manifest with the sketch's id when downloading a zip. This information is passed back to openprocessing when the child sketch is uploaded. Inspiration: MIT Scratch.

It's a great idea to build collections in any case!
But in the meantime there are so much rubbish collections that disfigure that page.
My idea is to delete all collections with no links after one day of creation (and may be some additional cleanup actions).
That would regenerate the collection side to what is was builded for - a side that provides a helpfull overview to interesting sketches!

1) Allowing link for a OpenProcessing sketch that may look like that:
[link:123]the name of the sketch[/link] where 123 is the visualID of the sketch.
2) Allowing external link like [url=http://en.wikipedia.org/wiki/Mandelbrot_set]the famous Mandelbrot set[/url].
3) And a link to the portfolio of the user who is commenting (by clicing on his logging name under 'comments'.

With some sort of messaging system, or better commenting system or simply more social networking feature aka all user has a micro bloging system - like facebook status.

I am not sure that is the goal of openprocessing but I would love to see a social network being developed around processing. The processing forum is good - but it's a forum lacking this layer of interactivity that social networks offer.

beside the sketch thumbnail (but without opening it) it would be nice to have an idea of the number of comments that have been written (and even something like a "new" label when the last comment is fresh)
